Radioimmunoassays have been used to detect digoxin-like immunoreactive factors (DLF) in the plasma and urine of hypertensive patients and rats with deoxycorticosterone acetate (DOCA)-salt hypertension. Uninephrectomized rats (n = 9), given 15 mg DOCA . kg-1 . wk-1, were fed a standard rat chow

A three-step chromatographic procedure was developed for purification of cardenolide 16'-O-glucohydrolase (CGH) from Digitalis lanata Ehrh. leaves, including Phenyl-Sepharose hydrophobic interaction chromatography followed by SP-Sepharose cation exchange and Q-Sepharose anion-exchange

Lanatoside 15'-O-acetylesterase (LAE) from in-vitro-cultivated cells of Digitalis lanata Ehrh. was isolated and partially sequenced. The enzyme was extracted with citrate buffer from acetone dry powder. It was purified in a two-step chromatographical procedure including Phenyl Sepharose hydrophobic

N-Terminal truncated forms of progesterone 5β-reductase (P5βR) were synthesized taking a full-length cDNA encoding for Digitalis lanata P5βR with a hexa-histidine tag attached at the C-terminus (rDlP5βRc) as the starting point. Four pETite-c-His/DlP5βR constructs coding for P5βR derivatives

Specific corticosterone binding to calf adrenal cortex plasma membrane was measured using the biologically active radioligand [3H]corticosterone. Corticosterone binding was found to be time-dependent, saturable and reversible, and was reduced by more than 70% when membranes were pretreated with

Programmed cell death (apoptosis), a form of cell death, described by Kerr and Wyllie some 20 years ago, has generated considerable interest in recent years. The mechanisms by which this mode of cell death (seen both in animal and plant cells), takes place have been examined in detail. Extracellular
